The subject of picking is both a rendering and a collision detection problem, with the majority of research being on optimizing the ray-scene intersection problem. Several algorithms that solve the picking problem exist in the context of rasterization, but all of them lack several of the features of our proposed solution while, with one exception, all being much more expensive in terms of computational time. We propose a novel single frame method which is able to correctly select not only primitives but also any type of objects that may appear on the screen at a fragment level including hardware instanced, alpha culled, hardware tessellated, hardware animated and particle systems. The proposed technique has optimal memory requirements and offers the opportunity to pick at micro polygon level and is not limited to the first contact, offering the full intersection list per ray if required to do so. The proposed technique offers further unique opportunities such as flexible fuzzy object selection and is the only technique that selects without disregarding opacity accumulation from transparent objects.","PeriodicalId":285027,"journal":{"name":"Computer Science in Cars Symposium","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121999388","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Two hypotheses are tested relating the symmetry groups of the model described by the geometric transformations that leave unchanged the offer variation graph with the symmetry group of the price variation graph. The results suggest that a change in the pattern of inflation is associated with the change in the symmetry groups.","PeriodicalId":285027,"journal":{"name":"Computer Science in Cars Symposium","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122802050","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As a solution to the above problem, this paper proposed a fuzzy group decision making multi attribute method based on a combination of fuzzy Simple Additive Weight (SAW) method and maximizing set and minimizing set defuzzification method. The defuzzification method is applied for CPs services ranking. The method is based on triangular fuzzy numbers and aims to aid decision makers (DMs) to evaluate and then rank CPs services. We illustrated the applicability of the fuzzy group decision making multi attribute method using a case study.","PeriodicalId":285027,"journal":{"name":"Computer Science in Cars Symposium","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123749265","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
